7 Claims.

My invention relates to that class of machines such as described in myReissue Patent No. 18,931, and more specifically to the utilization of apress of the cylindrical roller inking type for printing.

My invention has for its object to provide a construction whereby astandard press of this type may be changed so as to be adapted forprinting spots of wax carbon compound. As stated in my patent abovereferred to, I have discovered that it is essential to maintain therollers and type bed with which the carbon compound comes in contact ata predetermined temperature and that unless such temperature ismaintained the work turned out by the'press will be extremelyunsatisfactory, although in appearance it looks all right.

The principal object of my invention is to accomplish this result byhaving every roller 20 carrying the compound in contact with a heatedroller. I have found in practice that if this is done the heated rollerwill maintain the unheated one at the required temperature so that thepress will turn out satisfactory work.

A further object of my invention is to provide means whereby one of thethree traveling rollers can be heated continuously during its travelthereby maintaining the temperature of the rollers which contact it.

My means of accomplishing the foregoing objects may be more readilyunderstood by having reference to the accompanying drawings which arehereunto annexed and are a part of this specification, in which- Fig. lis an elevation of one side of a platen press provided with myimprovement;

Similar reference numerals refer to similar parts throughout the entiredescription.

As shown in the drawings the press is a standard press of this type andI shall therefore omit a description of the same except where thestandard parts are altered by being equipped with my improvement.

The press is provided with an ink fountain I, this fountain is adaptedto contain a quantity of wax carbon compound which is melted by means ofheating elements mounted adjacent the fountain as shown in my patentpreviously referred to.

The fountain is equipped with the usual blade 2 for regulating theamount of compound to be carried by the ink roller 3, adjusting screws 4f the usual type being provided for this regulation. Inside of the inkfountain roller 3, I mount an electrical heating element 5. This elementis preferably mounted in a cylindrical sleeve 6. The element is providedwith two lead wires I and 8 which are connected to commutator 9. Thiscommutator is engaged by brushes I0 and I I connected to electricalconductors I2 and I3 which lead to a source of electric current supply(not shown).

This commutator 9 is secured to the shaft I3 of the ink fountain rollerwhich is positively driven by the means of a chain I4 engaged by asprocket I5 mounted upon the shaft IS. The chain I4 is driven bysprocket (not shown) mounted upon the counter shaft I6 of the presswhich is driven 'in the usual manner by means of a chain II whichengages a sprocket I8 mounted upon the counter shaft I6, the chain beingdriven by a sprocket I9 mounted upon the' main shaft 20 of the press.

The ductor roller 2| is carried by an arm 22 by means of which it isoscillated in the usual manner between the ink fountain roller 3 and thecylindrical inking roller 23. This latter roller is mounted upon a shaft24 which carries a sprocket 25 which is driven by means of a chain 26which is driven by a sprocket (not shown) mounted upon the counter shaftI6.

The cylindrical inking roller 23 is provided with an electrical heatingelement 21. the shaft of which carries a commutator 23 which isconnected by brushes to lead wires 23 and for the purpose of conveyingcurrent to the heating element 21.

Distributing rollers 3|, 33, and 34 are mounted in the conventionalmanner so as to contact with the surface of the cylindrical inkingroller 23. The one end of the shafts of rollers 3|, 33, and 34 iscarried in supports 35, 33, and 31. The other ends, as clearly seen inFig. 5, are provided with spur gears 33, 33, and 43 which are driven bya gear 4| which is carried by the shaft 24 of the cylindrical inkingroller.

As stated in my patent hereinbefore referred to, I have discovered thatthere is an entire absence of tack in the wax compound when it is heatedto 'the temperature requested for satisfactory work. As a consequence itis necessary for all of the parts which carry the compound be;positivelydriven. By driving the distributing rollers in the manner described itwill be apparent that an even distribution of the melted wax compoundcan be maintained on the surface of the inkin roller 23.

The vertical type bed 44 is provided with a plurality of electricalheating elements 45 one of which is shown in Fig. 10. As shown these arefour innumber and a thermo couple 43 is mounted intermediate two innerones for the purpose of affording means for controlling the heat. Aprinting plate 41 may be secured to the type bed 44 in the usual orconventional manner. The platen 43 is operated in a standard way forpresses of this type. There are two rollers 43 and 53, the function ofwhich is to ink the printing plate 41 which is secured to the type bed44. A distributing roller 5| rides the two inking rollers 43 and 53.

The distributing roller 5|, is carried by a shaft 52 which is mountedabove the two traveling form rollers 43 and 53, the roller 5| being incontact with each of them. These rollers 43 and 53 are mounted uponshafts 53 and 54 respectively. At each end of the shafts 53 and 54, ofthe rollers 43 and 53, are provided wheels I3 and II which are not inline with each other but each roller wheel is adapted to register withone of two depressions I2 and 13 formed in the track I4, with the resultthat both rollers 43 and 53 will come in contact with the cylindricalinking roller 23 at the same time. The roller 5| is provided with anelectrical heating element 55 which is suitably connected by means of acommutator 53 to brushes 51, the latter being connected to lead wires 53and 53 leading to a suitable source of electric current supply (notshown). The form rollers 43 and 53 contact the surface of thecylindrical inking roller 23 from which it receives the melted waxcompound for the plate 41. In their rotation the roller 5| serves as atraveling distributor roller distributing the compound on the formrollers 43 and 53, as this group of rollers travels from the point ofcontact with the cylindrical inking roller 23 to and across the plate41- which is secured to the type bed 44.

It is apparent from the foregoing description that the conductors 53 and59 connecting the brushes 5! to the source of electric current supplymust be flexible so as to permit this travel.

It has also been found desirable in practice to to their extreme upwardposition shown in Figs. 4 and 6.

I accomplish this result by means of a reel 33 which is carried on anysuitable mounting intermediate the traveling rollers 43, 53, and 5| andthe source of electric current supply. The reel comprises a stationaryshaft 3| which passes through a'bearing and has two spaced circular sideplates 32 and 33 which form therebetween a circumferential groove. Imount a helical spring 34 in the spaces intermediate the plates 32 and33 and attach the inner end of the spring to the stationary shaft 3| andattach the outer end of the-spring, by means of a pin 31, to one of theside plates whereby the reel 33 will be uniformly impelled to onedirection.

The flexible conductors 53 and 53 pass from the brushes 5! around theperipheral groove of the reel 33 and are firmly attached to the reel bymeans of a shoe I2 pressed into engagement with the flexible conductors53 and 53 by means of a screw 13 passing through an. ear H on one of theplates of the reel, the spring 34 is arranged to exert a continuous pullupon that end of the flexible conductors which is attached to thetraveling distributing roller 5| so that when the rollers travel alongtheir tracks to a position farther removed from their upper position theconductors 53 and 53 will be held taut though at the same time they willunwind from the reel and when the traveling rollers are moved on theirtracks closer to the reel the latter will wind the flexible conductorsupon it thereby taking up any slack in said flexible conductors.

It will be apparent from an inspection of the drawings in connectionwith the foregoing description that in every instance I provide forcontact of an electrically heated roller with an done by means of gearswhich may be either toothed spur gears or grooved friction gears. My

Reissue Patent No. 18,931 clearly describes'means for accomplishing thisresult.
